摘要: A disc cutter bar including an upper part and a lower part which are welded together along an edge to form a housing for a row of gear wheels through which cutter discs are driven. The bar is provided with an elongation extending rearwardly in cross-section from the gear wheel row, which partly results in an increase of the stiffness and strength of the bar with a simultaneous low constructional height and partly makes it possible to increase the oil amount in the housing.

摘要: A mowing machine has a frame with driving wheels, which are adjustable in height, and a yoke carrying a cutter beam. The yoke is suspended from the frame such that it can move up and down with respect to the frame, and the cutter beam is swingably journalled on the yoke. The yoke and the beam are balanced by an upwardly directed spring force. Minor elevations on the ground make the cutter beam swing upwardly so that it is just the weight of the cutter beam itself which is accelerated.
